摘要： A process of producing methyl methacrylate polymers is provided wherein the monomer are polymerized by a bulk polymerization procedure at 150.degree. to 180.degree.C with a conversion of 50 to 80% and the volatiles predominantly comprised of the unreacted monomer, separated from the polymer product, are cyclically reused as a part of the monomer feed for polymerization. In such a monomer feed cycle system, oligomers are substantially removed from the volatiles and then the volatiles are blended with a virgin monomer feed for polymerization, the content in the volatiles of impurities having boiling points of lower than 200.degree.C at normal pressure is maintained within the range of 5 to 20% by weight.
